[PATCH v1 2/2] PM / AVS: SmartReflex/class3: Fix order of initialization of SR class and SR driver

From: Andrii Tseglytskyi
Date: Thu May 30 2013 - 06:44:37 EST


SmartReflex consists of three entities: SR device, SR class and
SR driver. SmartReflex driver depends on SmartReflex class, but
order of their initialization is not clear. They both use
late_initcall(), and order depends on Makefile calls.
Patch moves initialization of SR class to device_initcall(),
and removes redundant call of sr_late_init().

This provides predictable order of SmartReflex initcalls:
1. device_initcall() -> SmartReflex class init
2. late_initcall() -> SmartReflex driver init
